One England fan who escaped the violence and watched the footage back said:

It’s chilling. They clearly wanted to record every kick and every punch. It’s like a hooligan video game.

French police are yet to arrest the Russians in the footage, who were wearing black t-shirts, knuckle dusters and ski masks as they attacked rival fans.

Authorities also admitted they have no idea where the yobs are right now, meaning more violence is expected.

Marseille chief prosecutor Brice Robin described the gangs as ‘hyper-violent and hyper-rabid’ and called them ‘extreme and well trained’.

Last week, English police urged any ticketless England fans to go to Lille to support their team – but Russia play Slovakia there on Wednesday, potentially endangering the thousands of travelling Brits who have settled there.

UPDATE: Russia have been given a €150,000 (£119,000) fine and a suspended disqualification for crowd trouble following England vs Russia last Saturday.

29 Russian fans have also been deported from France, after a supporters bus was stopped near Cannes earlier today.

Alexander Shprygin, president of the Russian Supporters Union, told Reuters:

They want to deport almost 50 people including women who did not take part in anything. The police are making up for their mistakes three days ago. We are in a bus in Cannes and we have been blocked in by riot police. We are not going anywhere for the time being.
